#143 Add continuous jog input pins to Motion

[Sebastian Kuzminsky]

As of 2.7, jogging is done through the UI or via Motion's axis.N.jog-* HAL pins.

The problem is that Motion's HAL pins only provide jog-wheel jogging, not continuous jogging. For continuous jogging you need to go through the UI and Task, both of which are not realtime. This leads to lag between when the continuous-jog button (on the keyboard or in the GUI) is released, and when the jog actually stops.

This feature-request is for continuous-jog HAL input pins in Motion. This would provide an entirely realtime continuous jogging interface, assuming you have a realtime HAL component providing access to physical hardware jog buttons.
